Calculating Resultant Force

The unit for acceleration is m/s^2. So the correct answer is A = 3/15 m/s^2. In summary, the resultant force for the box is 3N and the acceleration is 3/15 m/s^2.

I'm I on the right track here?

Homework Statement


Determine the resultant force and acceleration for a box of mass 15kg being pushed with a force of 9N and a force of friction 6N acting to oppose.

Homework Equations



Force = Mass * Acceleration

The Attempt at a Solution



Force = 9N
Resultant Force = 9N - 6N = 3N (is this correct?)

Mass = 15Kg
Therefore,

3 = 15 * A
A = 3/15 m/s (this can't be right, can it?)

yes

Why not? But although your magnitude is correct, your units are off.
 

1. What is the formula for calculating resultant force?

The formula for calculating resultant force is F = ma, where F is the resultant force, m is the mass of the object, and a is the acceleration.

2. How do you find the direction of the resultant force?

The direction of the resultant force can be found by using the trigonometric function tangent (tan) of the angle between the force vectors. The angle can be determined using the inverse tangent (arctan) function.

3. Can resultant force be negative?

Yes, resultant force can be negative. A negative resultant force means that the forces acting on an object are in opposite directions, resulting in a net force of zero.

4. How do you calculate resultant force when there are multiple forces acting on an object?

To calculate resultant force when there are multiple forces acting on an object, you will need to break down the forces into their horizontal and vertical components. Then, use vector addition to find the resultant force by adding the horizontal components and the vertical components separately.

5. What are some real-life applications of calculating resultant force?

Calculating resultant force is important in various fields such as engineering, physics, and sports. It is used to determine the stability and structural integrity of buildings and bridges, to calculate the trajectory of a projectile, and to analyze the forces involved in sports movements such as throwing, kicking, and jumping.
